Looking from the back of the 8650 counter with the lid open, there is a safety switch on the left side. It is either not pressed in when the lid is closed or it is broken. To test, take the two wires from that switch and connect them together. That will by pass the switch and allow the machine to work. Good luck.

Minolta 8650 problem c-2a01

loo like you replaced the cyan toner cart.. (with the machine powered off and unplugged) take a look inside the machine with the cyan toner cart out.. make sure that nothing is blocking the metal contacts or if there are dirty contacts. perhaps there is a piece of debris that is blocking the connection of the new toner cart to the printer. another thing to check is the contacts on the toner cart its self.

The motor on my riccar 8650 is very loud. is there brushes that can be replaced?

Your. 8650 is likely well over 20 years old. It has carbon brushes in the motor that may need replaced but your best bet Is to take it to your Riccar dealer to diagnose it or you might replace the wrong thing. You have a very durable long lasting machine obviously but there are minor things that need occasional service to keep it running properly for many more years. This series started with the 8600 models of which I still have many brought in for annual service. There has been an 8700 and 8800 series and now the latest 8900 series which has been out well over 10 years.

HP DL585 G2 Machine Check Exception

This problem has been seen for awhile on all flavors of hardware: CPU X: Machine Check Exception: 0000000000000004. In can come from a kernel recompile after new drivers have or havenot been upgraded. Upgrading OS on older hardware can cause this exception throw. At any rate your system is now rendered unstable and probably should be returned to the last good known configuration - so goes the old addage - "upgrade or die!"
